A 'Triptych' art box would make a very cool asset for a museum or fancy palace, as an activator with opening doors.

Here's a video on one of the most famous Triptych's, which in itself is a fascinating breakdown of all the symbolism contained. Really interesting how Bosch depicted hell as a world where everything in it was man-made and nature no longer existed...

Anyways, I think this would make a pretty cool unique asset in a very fancy imperial location, and a good artist could make something really remarkable.

Maybe the 3 panels could could each represent one of the 3 Era's? And when closed the box could show what they believe to be a map of Nirn?
